Am I crazy?

My daughter will be one month old this Sunday and I have this thing about letting other people hold her. I get so anxious and upset when certain people hold her and I don’t understand it. I’ve talked with my doc about postpartum depression and I’m definitely struggling with it.. is being anxious when others hold baby and not wanting others to hold baby a part of postpartum depression? I feel guilty for feeling the way I do. I don’t like when almost anyone on my fiancé’s side of the family holds her, and I don’t like when certain family members of mine hold her. My biggest issue comes from my mil and my fiancé’s grandma holding her. I feel this sense of threat from them and I don’t understand it. I try so hard not to feel that way and I never act on how I’m feeling but as soon as my daughter cries with one of them I get this panic feeling like I need to take my baby back right away. I get upset when those two are even around the baby and I because I don’t want to share with them so bad. I mean yes they’ve said things during my pregnancy and after my daughter was born that have really gotten under my skin so that might be a part of it (my mil likes to call my baby her baby, and basically demanded to be at the hospital when baby was born thankfully they weren’t though because I had a c section at 9pm, and they feel the need to feed my daughter every time they come over and it makes me mad because I want that bonding experience). I just don’t know why I’m so overprotective.

I’m dreading the 4th of July picnic because I know people will want to hold my baby and I honestly don’t want to share... what do I do...
